On this board the OHCI port's power control and over-current signals from
TPS2065 power switch are connected via GPIO2[4] and GPIO6[13] respectively,
so we can implement the DA8xx OHCI glue layer's hooks for overriding the
root hub port's power and over-current status bits.
We also have to properly set up the clocking mode in the CFGCHIP2 register,
so that internal 24 MHz reference clock is fed to the USB 2.0 (MUSB) PHY and
its output is used to clock the USB 1.1 (OHCI) PHY...

This is the third copy of OHCI platform setup code which is almost
the same except for the GPIO numbers.
Well, in my counting, it's only second, DA830 EVM being the first one.
What's the third?
Can we attempt to consolidate
the GPIO case under drivers/usb/host/ohci-da8xx.c glue layer itself?
Of course, here should be a provision for non-GPIO based implementation
as well.
Sergei, any thoughts, comments?
I designed the hub interface to be as abstract as I could, and now you're
proposing to add GPIO to it? No, I have no clear idea how to keeep it abstract
and add GPIO support at the same time. I would have been grateful to
TI if I didn't have to invent this at all and they stop saving on OHCI pins.
Thanks,
Sekhar
WBR, Sergei
